JACOB KAUFMAN N, PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO STEEL HEDDLEMANUFACTURING COMPANY, OF PHILADELPHIA, PENNSYLVANIA, A CORPORATION OFPENNSYLVANIA.-

HEDDLE.

To all whom it may concern:

Be it known that I, JAcoB KAUFMANN, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inHeddles, of which the following is a specification.

My invention relates to heddles and. in such connection it hasparticular relation to the type of heddles made from a thin flat stripof metal or wire.

The principal object of my invention is to provide a heddle of theaforesaid type with means to prevent turning of the heddles about theirlongitudinal axis while mounted on the rods of the harness frame.

In connection with the foregoing my invention also contemplates meansfor preventing the impropermounting of the heddles in the harness framein order that the warpeyes will all face the same way and properly nesttogether.

The nature and characteristic features of my invention will be morereadily understood from the following description taken in connectionwith the accompanying drawing's forming part hereof in which:

Figure l'is an elevation of a harness frame having heddles embodying themain features Of my invention mounted therein. Fig. 2 is an enlargededge View of a heddle embodying the main features of my invention, Fig.3 is a face view thereof, and Fig. 4t is a section thereof taken on theline 1-4 of Fig. 2'with a portion of the heddle frame rod shown in connection therewith.

In the particular embodiment of my invention shown in the drawings, 5 isa heddle made from a thin flat strip of metal or wire having a warp-eyeformed by first slotting the strip at or near the center thereof andthen expanding orbending the shanks of the slotted portion out of the'11'15111'1 plane of the heddle proper, as clearly shown in Figs. 2 and3 of the drawings. It will, .of course be understood that the shanks ofthe warpeye may also be expanded laterally to extend beyond the sideedges of the strip, as is well known to those skilled in the art. Theheddleis also'provided at its upper end with a mortise 8 and at itslowerend with a mortise 9 for mounting the heddles in the Specification ofLetters Patent.

Application filed April 29, 1910.

Patented July 4, 1911. Serial No. 558,320.

" harness frame on the-usual heddle rods orbars 10 and 11. The mortises8 and 9 may if desired be first formed in the manufacture of the heddlesin the manner shown and described in Letters Patent No. 748,713 grantedto William Fehr, September 18, 1903, by first slotting the strip fromwhich the heddle is formed near the ends thereof and thereafterexpanding the respective shanks l2 and 18 laterally by swaging the metaladjacent the ends of the slots as at at the upper end of the heddle arethen formed into a sinuous conformation so as to provide each shank withbearing portions extending some distance on each side beyond the planeof the heddle proper, which bearing portions will serve to preventrotation when the same is in use and subject to the tension of the warpthreads passing through the central warp-eyes.

form of each of the shanks 12 of the upper mortise 8 is of a shapeapproaching an elongated letter 8 "so that the heddles when mounted inthe frame will readily nest together to thereby permit a large number ofheddles to be mounted on the rods in close relationship, and furtherthat while each shank of said mortise is of the same shape they arecomplemental but not parallel each other. It should] also be noted thatthe warp-eyes 7 will nest together in a similar manner, providing theproper ends of the. heddles are mounted'on the proper upper and lowerrods 10 and 11. v In other words. in the type of heddles made from athin flat strip of metal or wire with the warp-eyes formed as aforesaidthe warpeyes will always properly nest together if the upper end of theheddle be mounted on the upper rod of the frame it'being otherwiseimmaterial which face of any particular heddle is heddle in the frame;but if however, the heddles beturned end for end, the warp eyes will notthen properly nest as will be readily understood by an inspection andconsideration of Fig. 2 of the drawings. To prevent the aforesaidimproper mounting of the heddles in the frame, one mortise 8 only ispreferably made of the peculiar conformation contemplated by the presentinvention .of the heddle about its longitudinal axis presented to thenext adjoining l4 and 15. The shanks 12 of the mortise 8 It should benoted that the preferred with and the mortise 9 at the other end thereofE is left in its plane condition so that any attempt to mount theheddles on the rods With the Wrong end uppermost will be readilyapparent. It should be understood-however that the shanks of both upperand lower mortises may be formed as herein described Without departingfrom the main purpose of my present invention.

Having thus described, the nature and characteristic featuresv of myinvention, What I claim as new and desire to secure by Letters Patentis:

1. A heddle made froma thin fiat strip of metal or Wire having a mortisefor mount= ing the heddle 0n the harness frame rods, the shanks of saidmortise extending out of the plane of the strip in both directions insinuous form and of opposite curvature on I either side.

shanks of the other extending out of the plane of the strip in bothdirections in sinuous form and of opposite curvature on either side.

In testimony whereof, I have signed this 7 specification in the presenceof two Witnesses.
